A SPECT scan was used to take special images of your bones.

The scan involves injecting special materials directly into a blood vessel. The materials accumulate in particular areas of the bones, depending on their properties. The special materials give off weak radiation for a certain time. This enables a special camera to measure how much of these materials have accumulated in specific areas.

To do the scan, the person usually lies on a bed in a large piece of equipment that takes pictures of the inside of the body. At the same time CT images are produced using X-rays, and images are produced by the special camera. A computer overlays these images, produced in different ways, on top of one another. This enables an assessment of how active the cells in the bone are.
